- 26. Low Cost of Change Using Docker Developers • Compile/Build • Seconds Extend container • Package dependencies • Seconds PaaS deploy Container • Docker startup • Seconds
- 27. Low Cost of Change Using Docker Fast tooling supports continuous delivery of many tiny changes Developers • Compile/Build • Seconds Extend container • Package dependencies • Seconds PaaS deploy Container • Docker startup • Seconds
- 28. Change One Thing at a Time!
- 29. What Happened? Rate of change increased Cost and size and risk of change reduced
- 30. Cheaper - Lean
- 31. “Freedom and responsibility” Reed Hastings 2009
- 32. Fail early and often Instrument everything Hypothesis driven development Efficient and autoscaled
- 33. Efficiency Gains: Virtualization consolidates CPUs Docker consolidates CPU and RAM
- 34. With Docker a test environment should only exist for the few seconds it takes to run a test
- 35. Autoscale production to consume just the resources you need, by the second
- 36. Safer - Rugged
- 37. “Developer Defined Infrastructure” Jerry Chen 2015
- 38. What can developers do about the threats?
- 39. External Threats Build using penetration test tools Manage image supply chain Hardened immutable services Service roles and security groups
- 40. Internal Threats Assume employees are compromised User roles, minimum privilege Audit logs for everything Encrypt data at rest
- 41. Patterns and practices
- 42. In Production https://www.docker.com/resources/usecases/ and many more….
- 43. Patterns and practices
- 44. Best Practices https://blog.docker.com/2015/05/understanding-docker-security-and-best-practices/
- 45. Immutable deployments Automated penetration testing Role based identity and access Trusted container supply chain Continuous audit
- 46. Workloads
- 47. Need for Speed CPU and IO Intensive workloads Hadoop, streaming, datastores Bare metal for efficiency Well isolated for security
- 48. Cutting the Cost Many similar containers per VM Saving on RAM, oversubscribe CPU Deploy with Swarm, Mesos, ECS, GKE VM based single tenant security
- 49. Playing it Safe One critical container per VM Extra security for exposed services Deploy as immutable VM image Docker adds to VM security
- 50. Tooling for Docker and many more….
- 51. Docker in Production 2014 - DIY frameworks 2015 - Hardening and best practices 2016 - Mature production tooling
